Question

In Object Oriented programming C++ : Write the appropriate functions for Student to neatly display a Student, and then finally GPA. Have items neatly line up in columns.

I need help creating a derived class called student that finds GPA (between 0.0 and 4.0) and credits completed (between 0 and 199).

Answer 1

Source code:

#include <iostream>
using namespace std;

struct student
{
    char name[50];
    int roll;
    float Credits;
  
};

int main() 
{
student s;
    cout << "Enter the student information," << endl;
    cout << "Enter the student name: ";
    cin >> s.name;
    cout << "Enter roll number: "<<endl;
    cin >> s.roll;
    cout << "Enter Credits Completed(0 to 199): "<<endl;
    cin >> s.Credits;
   
    cout << "Displaying Information," << endl;
    cout << "Name: " << s.name << endl;
    cout << "Roll: " << s.roll << endl;
    cout<<"GPA and Grade: "<<s.Credits;
      
       if (s.Credits>150){
cout << "GPA 4 Grade: A"<<endl;
        }
        
        else if(150>s.Credits>100){
            cout<<"GPA 3 Grade: B"<<endl;
        
        }
            else if(100>s.Credits>50){
                cout<<"GPA 2 Grade: C"<<endl;
            }
                else if(50>s.Credits){
                   cout<<"GPA 1 Grade: D"<<endl;  
                } 
    
    return 0;
}

The output:
